View Full Version : Is it worth it?

I've just been told I need a new automatic transmission but it will cost me $4,000 for a reconditioned one. The car isn't worth that and I don't have $8-9k for a new car. One thing someone said is that since I got the cylinder head got replaced that I would basically have a whole new engine so should last many years. Is it really worth spending $4k to get it fixed?

You don't need a new one, a good second hand one should cost you less than $500-600 plus labour to fit.

If your mechanic is trying to slug you $4k, they either don't want the job, or they plan on taking you for a ride. I'd find someone else to work on your car.

But if I get a second hand one who knows if it will have the same problem as mine in time?

Well, all these things break over time, that's what they're designed to do. Get a low km unit and make sure you do regular trans fluid changes and it'll probably out last the rest of the car.

Or sell it, redo your license and buy a SRi

$4k lol. The mechanic is trying to rip you a new one.

Like I said to you the other night. Brand new one installed will be about $4k.

I can't believe it would be that much considering an entire engine and fitment for my Astra was under $2k... Different jobs I know but I wouldn't think a gearbox would cost more than an engine to supply let alone install.

You could do a fullrebuild and shift kit etc etc on about any auto car for half of that. Your mech is a crook. Do like Chris said and find a lowish km s/h one or bite the bullet and get a manual licence and buy a SRi.

Thanks for your opinions guys I think I've worked out what I'm going to do, I can get a recon one for $2,800 inc fitted but I will wait till it gets worse and if I have a full time job by then I'm going to get a loan and get a Mazda 3 but if I don't I'll just fix mine

Still, for what it's worth, a good second unit would be a lot less. I'd only buy a new transmission if I planned on keeping the car for a very long time, like 10 years or more. Thing is, most automatic small cars like the XC Barina are usually very low km and it's not hard to find a second hand box on the cheap. I just don't see the point in blowing that much money on a gearbox if you don't need to, particularly if you're not planning to keep the car long term.

As I said, if you get a low mileage box, do regular transmission servicing along with your regular servicing and it'll last years. Plus, most wreckers will usually give you some sort of warranty with a gearbox.

Thats still a decent amount of $$$. Why not sell your current xc for say 2k, buy a decent sri for 5k. You have a much better car for the same money as you would have spent on the trans

There were a couple of SRi's recently that were sold for around the $2k mark here in Adelaide I know of. One was in fairly good nick too. Just beware with the Z18XE, the ECU is the weakest point and if it's been replaced at some point (in which case most have), the car will be a lot more reliable than some people would have you believe.

And the Mazda 3 is, well a Mazda 3. Unless it's a MPS or SP23/25, it'll be as boring as bat turds.

Hers was one, there was an Aruba Blue one that went soon after (not my ex's car), sold by a guy on CCU. Both were pre-facelifts, although Rachael's car was far tidier and it had the ECU replaced too.

And way way wayyyyyy slower ;)

Plus once ive hacked the ecu, you can add an exhaust, decent filter setup, cams and get a free tune, and still spend half of what you would on a mazda 3 ;)

Half the money, 2/3 more oomph and twice the fun :lol:

Pick one :) unless its a 7 speed DSG unit from VW its one or the other.

ran some calculations on how the AMR500 supercharger would fair up on the Z14XE

Supercharger: AMR500 (Small i know but hear me out)
Dimensions: 170mm Long x 180mm wide x 130mm tall
Displacement: 500cc per revolution.
Safe working limit: 16000rpm

1.4L x 6500( Assumed redline) = 9100/2 = 4550 liters per min
5(psi)+14.7(psi at atmo) = 19.7/14.7 = a boost ratio of 1.340 br

Air requirement at Boost
4550(lpm)x1.340(br) = 6097 Liters per min at 5psi at 6500rpm

Charger rpm required
6097/0.5(charger displacement) = 12194rpm (safe working limit for the AMR500 is 16000rpm)
Pully ratio required
12194/6500(redline) = 1.876:1

Unsure of the Drive belt pully size on the Z14XE But can always work that out later

HP increase figures are as such:
1.4x8hp = 11.2hp (rough power increase per 1psi of boost)
11.2hp x 5psi = 56 hp
90hp (factory) + 56 = 146hp at the flywheel (not accounting for HP loss to drive the supercharger)
146x0.745= 108kw at the flywheel (not accounting for kw loss to drive the supercharger)
torque would equal 161nm at the flywheel @6500rpm, Substantially more lower down in the rev range(not accounting for HP loss to drive the supercharger)
= 42kw/51nm gain at 5psi

Pop in some z18xe injectors which will hopefully fit, Tune the ECU, Pop an exhaust on and have some fun :)

Unsure what the strength of the auto box is though. that would be the real question if it could keep up with the power.

Two things, the auto box is an AF13 in this model. I would guess this is an equivalent to the F13 manual box. I know the F13 is capable of handling a stock Z18. Astra I think uses the AF17, which could possibly be a direct fit into the Corsa.

Other thing is, the Z14XE uses the Delphi HSFI 2.1 ECU, yet another different ECU in the Corsa C.

Delphi has been unlocked and cracked already then =) can provide the files/ forum link when im at my desktop again if wanted.

Keep yours, buy second hand box for 500, get guy to replace it for love and a case of beer, save and upgrade to z18xe as chris said it bolts up (i think) win at life, mod the 1.8 with go fast bits =)

Ah, that puts mine out then as the engine's over 100,000ks now :(

Still, could be good if you want to daily it around for a bit then mash it and the Corsa together!

Im a bit late back in to this one, but on the topic of Mazda3. I am not sure what you're all saying about slow. Yes they arent a blistering turbo V8 putting out 67 billion killerwasps of power, but they are definitely punchier than the corsa.

Then again, I am referring to the SP23 models, not the 2.0L models (which I cant vouch for)

SilentShout
31st July 2015, 10:54 AM
Only thing is finding a decent sp23 model. They require premium fuel however most were bought by rather aged people who believe e10 is gods gift to motorists.

If theres one in good nic then it will be a beautiful reliable and zippy car, but it will come with a price tag.

Oh and the sp23 is 3 car lengths slower than a corsa c sri ;) that i can tell you from experiance.
